Vibevoice ASR
Microsoft's Vibevoice ASR is a unified speech-to-text model capable of handling 60-minute long-form audio in a single pass, generating structured transcriptions with speaker, timestamp, and content information. It is genuinely best at processing long-form audio and producing rich transcriptions, with support for customized hotwords and over 50 languages.

Frequently asked questions about Vibevoice ASR
Answered from the entry's own fields: context, license, modalities, evidence, serving and the memory to self-host.
Vibevoice ASR advertises a context window of 64,000 tokens. The figure is the creator's published maximum; a given host may serve less, and the gateway routes on what each host actually serves.
Yes. Vibevoice ASR is an open-weight model released under the MIT license, so the weights can be downloaded and self-hosted within that license's terms.
Vibevoice ASR accepts Audio and produces Text. The capabilities card on this page lists which API features each deployment honours, such as function calling and structured output, with the source each was checked against.
No published benchmark result for Vibevoice ASR is in the catalog yet, so the model is shown as unmeasured. It is not ranked or estimated; the router treats it as unknown for every task until a suite measures it.
Not on the managed pool today; Vibevoice ASR is listed for reference and comparison. Connect your own provider key or endpoint that serves it and the gateway runs it on your account, with routing decisions recorded the same way.
About 8.9 GB at INT8 for the weights and a default context, from the catalog's 8.7B parameter count; FP16 needs roughly twice that, and long contexts or many concurrent requests add KV cache on top. The GPU section on this page lists cards that hold it, and the capacity planner sizes it for your context length and traffic.
